fleit ltiioivn that lileiv-Yorlnin the countyr otNe'iv yYork and.

`State oi Newv .rforl-r, have invented cert-ain new and useful improvements inMli/lethods of Waking Hair Curlers, of which the following is a fulhclear, and exact description i This invention resides in a method oir" iiialting hair curlers of the type Vwhich rconsists of a feoi'e ot lead or similar Flexible and non-resilient materia-l enveloped in a suitable textile material and upon Which the. hair is wound and secured against unwinding by bending over the ends Aof the strip.

ln the manufacture ot my improved curler, :i suitable ilexiliile non-resilient. coresuch as lead or other similar metal. 'is 'formedinto a continuous strip havingportions there-ot it reduced ':i'oss-seitioii at .points spaced :ziairt a distance equal to the desired length oll :i ciirlei'. rlhis strip is c ated with glue and while the latter still sott is tightly enclosed in :i continuous textile envelope nliich closely lits the portions ot reduced cross-section. attci ivhich the strip andenvelope are completely divided at the re.- duced points. The enveloped strip may be sulijcctei'l to' a longitudinal tension to sever the iiietal at the points of reduced cross-section Without affecting the continuity oil the covering. prior to division of the enveloped sti-ip iiito thedesired lengths. This stretching pullsthe covering over the endsof the stripsto a slight extent to completely conceal the same.

ln the accompanying draiving:

lncarrying out the process l produce in any desired manner a strip l ot lead or other 'Flexible and non-resilient metal or material which may he tlator ribbon-likeas shown in l l. and 2.and which forms vthe core ot the curler. This core or strip is providedrat intervals throughout its length with pory l, yloi-interi W7.'

ordina-ry braiding machinewherein it is cov,

ered or.y enveloped n progressively `by a ytight fitting tubular braid 3, which may be ofcotton, Wool silk, or other suitable material. Before entering thef braiding machine the core or ribbon is caused to pass through a bath of liquid glue; `The glue forms a coat-` ing on the core andv causesfthe braided-covering to adhere thereto. The strands ofthe braided tabric being laidon the bias,"` the lfabric. ywill* yield longitudinally when stretched. Whenthe strip comes rornkthe braiding machine it h as the appearance shown generally in Fig. 3, the braid 3 closely fitting the tapered restrictions of the metallic ribbon. The enveloped ribbon is then divided at .the restricted points int-o `a series'of` sec- .tions or' ciirlers such as shown in Fig. Ll-. Since the braided covering closely lits fthetapered or reduced ends ofthe curlers and is glued throughout its length thereto, there will be no possibility of the metallic ribbon or core being pulled out or` its covering` dur-A ing the use of the curler, Because o5? the restrictedsection of the covering and the use ot adhesion, there will be little likelihood otv the ends of the braid unravelliiig or traying to expose themetallic ribbon or core.

Hit is desired to morecompletely protect the ends of the curler the enveloped ribbon shown in Fig may be subjected to a longitudinal tension or stretching, during which the portions of the braid along the neck or restricted portions will yield and extend longitudinally so that the strain is largely transferred to the weakened neck portions of the metallic ribbon with the result that `the ribbon breaks at the reduced portions Without affecting the continuity of the covering. As the,fracturedv ends of the metallic ribbon separate after fracture.v the braided covering will be further extended length and contracted in cross-section. The enveloped lribbon is then severed betweeny the fractured ends tol provide the individual curlers. Because the ends ot the braid are closely contracted there -Will be 'very little icov tendency to fray or unravel, particularly as the differentgstrands arecaused to adhere to each other' from the glue which'they take up from the core.

The vstretching of the strip in order to fracture the'rnetallic ribbon without affecting the continuity of the cover may he con veniently accomplished by passing the strip through two sets of rolls, the second of which runs at a slightly greater speed than the first, thus producing a strain on the run between the' two sets or rollers. rlhis may be accomplished, however, by subjecting the strip either to a sudden or gradual tension. The stretching ii desired maybe omitted entirely and the ribbon and covering divided latthereduced sections at a single cutting operation. The stretching, however, is pret'- erable, because the ends of the fractured metallic strip sections are then completely concealed and the article is therefore more attractive in appearance.

I claim: V

rhe'method of making hair curlers which comprises closely applying a continuous flexible extensible covering to a continuous core of a flexible non-resilient material having portions of reduced cross-section therealong at distances apart equal to the length or a cur-ler, stretchingthe covered core until the core is fractured at the points of reduced cross-section and the covering is longerthan the aggregate length of the fractured strips of the, core; and thencntting orl otherwise dividing the covering between the fractured ends.v
